One time password with Yubikey for PGP Desktop

we are using PGP Desktop and we are updating security at our company by adding one time passwords everywher(we can). For this purpose we will be using Yubikey's one time password mode. At Yubico they said that PGP Desktop doesn't suport one time password at the time but that it could be integrated in the software very easy and they would help with this process. Now i would like to know if this is possibile at all and who should i turn to?
